Question

What is the difference between variation and standard deviation?

Answer 1

Answer:

The variance is the average of the squared differences from the mean. Standard deviation is the square root of the variance so that the standard deviation would be about 3.03. ... Because of this squaring, the variance is no longer in the same unit of measurement as the original data.

Answer 2

Answer:

Answer:Variance is the average squared deviations from the mean, while standard deviation is the square root of this number. Both measures reflect variability in a distribution, but their units differ-

Step-by-step explanation:

• Standard deviation is expressed in the same units as the original values (e.g., minutes or meters)
• Standard deviation is expressed in the same units as the original values (e.g., minutes or meters)Variance is expressed in much larger units (e.g., meters squared).
